Abstract

The solution is a way to reduce dust and carbon oxides emissions in the solid fuel hearth of any power, as well as a boiler to reduce dust and carbon oxides emissions in the solid fuel hearth of any power. The main element of the boiler is the combustion chamber (1), which is divided into two parts, i.e. the lower part (2) of the combustion chamber (1) and the upper part (3) of the combustion chamber (1). The lower combustion chamber (2) is usually equipped with a slotted grate (4), which is preferably mounted obliquely or parallel to the ground level on which the boiler stands. Into the combustion chamber (1) the so-called primary air. This air is supplied from below, from under the slotted grate (4), using a blower (7). Above the grate (4), in the upper zone of the lower part (2) of the combustion chamber (1), there is a secondary aerator (8), through which secondary air is introduced. The most favorable combustion process is achieved provided that 10% to 50% of the secondary air is supplied, in relation to its entire quantity supplied to the furnace (1).
